Kurosan
From Sonic Retro
<forumuser name="Kurosan" /> Kurosan is a Sonic community veteran who has been hanging around various websites since the pre-2000 era. Generally lurking for months if not years at a time, his presence can be spotty. Hailing from the province of Québec in Canada, he currently resides in Alberta with fellow scener KojiChao. Has gone by the name REAL SONIC PRO in the past.
Though not particularly well known for much, he is the author of a somewhat widely distributed Christmas-themed hack of Sonic 1.
Occasionally does professional game testing.
